Subject: [PATCH 1/2] NetworkPkg: TcpDxe: SECURITY PATCH CVE-2023-45236 Relared
Patch
BUG: Tianocore's EDK2 TCP implementation generates ISNs using fixed
increments from a fixed base value and thus is uceptible to TCP session injection
and session hijack attacks.
This commit is a patch for CVE-2023-45236. Generates ISNs using RngLib to get a high-quality random number.

PixieFail Bug #8
CVE-2023-45236
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N
CWE-200 Exposure of Sensitive Information to an Unauthorized Actor
Updates TCP ISN generation to use a cryptographic hash of the
connection's identifying parameters and a secret key.
This prevents an attacker from guessing the ISN used for some other
connection.
This is follows the guidance in RFC 1948, RFC 6528, and RFC 9293.
RFC: 9293 Section 3.4.1. Initial Sequence Number Selection
A TCP implementation MUST use the above type of "clock" for clock-
driven selection of initial sequence numbers (MUST-8), and SHOULD
generate its initial sequence numbers with the expression:
ISN = M + F(localip, localport, remoteip, remoteport, secretkey)
where M is the 4 microsecond timer, and F() is a pseudorandom
function (PRF) of the connection's identifying parameters ("localip,
localport, remoteip, remoteport") and a secret key ("secretkey")
(SHLD-1). F() MUST NOT be computable from the outside (MUST-9), or
an attacker could still guess at sequence numbers from the ISN used
for some other connection. The PRF could be implemented as a
cryptographic hash of the concatenation of the TCP connection
parameters and some secret data. For discussion of the selection of
a specific hash algorithm and management of the secret key data,
please see Section 3 of [42].
For each connection there is a send sequence number and a receive
sequence number. The initial send sequence number (ISS) is chosen by
the data sending TCP peer, and the initial receive sequence number
(IRS) is learned during the connection-establishing procedure.
For a connection to be established or initialized, the two TCP peers
must synchronize on each other's initial sequence numbers. This is
done in an exchange of connection-establishing segments carrying a
control bit called "SYN" (for synchronize) and the initial sequence
numbers. As a shorthand, segments carrying the SYN bit are also
called "SYNs". Hence, the solution requires a suitable mechanism for
picking an initial sequence number and a slightly involved handshake
to exchange the ISNs.

Subject: [PATCH] Fix timing side-channel in ECDSA signature computation
There is a timing signal of around 300 nanoseconds when the top word of
the inverted ECDSA nonce value is zero. This can happen with significant
probability only for some of the supported elliptic curves. In particular
the NIST P-521 curve is affected. To be able to measure this leak, the
attacker process must either be located in the same physical computer or
must have a very fast network connection with low latency.
Attacks on ECDSA nonce are also known as Minerva attack.

Subject: [PATCH] evp: process key length and iv length early if present
evp_cipher_init_internal() takes a params array argument and this is
processed late in the initialisation process for some ciphers (AEAD ones).
This means that changing the IV length as a parameter will either truncate the
IV (very bad if SP 800-38d section 8.2.1 is used) or grab extra uninitialised
bytes.
Truncation is very bad if SP 800-38d section 8.2.1 is being used to
contruct a deterministic IV. This leads to an instant loss of confidentiality.
Grabbing extra bytes isn't so serious, it will most likely result in a bad
decryption.
Problem reported by Tony Battersby of Cybernetics.com but earlier discovered
and raised as issue #19822.

+ * Fixed an issue where checking excessively long DSA keys or parameters may

+ Applications that use the functions EVP_PKEY_param_check() or
+ EVP_PKEY_public_check() to check a DSA public key or DSA parameters may
+ experience long delays. Where the key or parameters that are being checked

From 2a0fa58af18f2ab5435ee2cefa6a02cacfb18818 Mon Sep 17 00:00:00 2001
From: hy <941973499@qq.com>
Date: Fri, 28 Mar 2025 22:48:57 +0800
Subject: [PATCH] Harden BN_GF2m_poly2arr against misuse. The
BN_GF2m_poly2arr() function converts characteristic-2 field (GF_{2^m}) Galois
polynomials from a representation as a BIGNUM bitmask, to a compact array
with just the exponents of the non-zero terms.
These polynomials are then used in BN_GF2m_mod_arr() to perform modular
reduction. A precondition of calling BN_GF2m_mod_arr() is that the
polynomial must have a non-zero constant term (i.e. the array has `0` as
its final element).
Internally, callers of BN_GF2m_poly2arr() did not verify that
precondition, and binary EC curve parameters with an invalid polynomial
could lead to out of bounds memory reads and writes in BN_GF2m_mod_arr().
The precondition is always true for polynomials that arise from the
standard form of EC parameters for characteristic-two fields (X9.62).
See the "Finite Field Identification" section of:
https://www.itu.int/ITU-T/formal-language/itu-t/x/x894/2018-cor1/ANSI-X9-62.html
The OpenSSL GF(2^m) code supports only the trinomial and pentanomial
basis X9.62 forms.
This commit updates BN_GF2m_poly2arr() to return `0` (failure) when
the constant term is zero (i.e. the input bitmask BIGNUM is not odd).
Additionally, the return value is made unambiguous when there is not
enough space to also pad the array with a final `-1` sentinel value.
The return value is now always the number of elements (including the
final `-1`) that would be filled when the output array is sufficiently
large. Previously the same count was returned both when the array has
just enough room for the final `-1` and when it had only enough space
for non-sentinel values.
Finally, BN_GF2m_poly2arr() is updated to reject polynomials whose
degree exceeds `OPENSSL_ECC_MAX_FIELD_BITS`, this guards against
CPU exhausition attacks via excessively large inputs.
The above issues do not arise in processing X.509 certificates. These
generally have EC keys from "named curves", and RFC5840 (Section 2.1.1)
disallows explicit EC parameters. The TLS code in OpenSSL enforces this
constraint only after the certificate is decoded, but, even if explicit
parameters are specified, they are in X9.62 form, which cannot represent
problem values as noted above.
Initially reported as oss-fuzz issue 71623.

Subject: [PATCH] SecurityPkg: Out of bound read in HashPeImageByType() In
HashPeImageByType(), the hash of PE/COFF image is calculated. This function
may get untrusted input.
Inside this function, the following code verifies the loaded image has
the correct format, by reading the second byte of the buffer.
```c
if ((*(AuthData + 1) & TWO_BYTE_ENCODE) != TWO_BYTE_ENCODE) {
...
}
```
The input image is not trusted and that may not have the second byte to
read. So this poses an out of bound read error.
With below fix we are assuring that we don't do out of bound read. i.e,
we make sure that AuthDataSize is greater than 1.
```c
if (AuthDataSize > 1
&& (*(AuthData + 1) & TWO_BYTE_ENCODE) != TWO_BYTE_ENCODE){
...
}
```
AuthDataSize size is verified before reading the second byte.
So if AuthDataSize is less than 2, the second byte will not be read, and
the out of bound read situation won't occur.
Tested the patch on real platform with and without TPM connected and
verified image is booting fine.
